I don't use any grease, but use the wonder wads on top of the powder then ram that down to seat it and then the ball. I have heard other people advocating that the ball should be as close to the end of the cylinder as possible and tried filler and using multiple wads to bring the level of the ball up, never noticed any improvement in accuracy, but I was shooting off hand. Even using the holy black, I have not had fouling problems while I used the wads. If you like doing things yourself, look to Gatofeo's posts, he has a recipe for a lube to soak felt in and make your own wads. My wife is a forgiving woman, but melting mutton tallow in the kitchen might put her at her limit, so I buy the wads. I do grease the cylinder pin with bore buttter because when I started shooting, I bought two tubes and still have it laying around. That keeps me shooting for 200 rounds without a problem. All in all, there are many ways to go and no one right answer, I avoid greasing the chambers because I typically shoot in the summer and in Missouri that can mean 100 degree heat with 95% hummidity and that grease just flows everywhere then. Enjoy that navy, I love mine.
